TIRE-rum.

To all whom t may concerm y Be it known that I, CHARLES M. STARR, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in rTire- Pumps, of which the'following isa specification. v f

The invention relates to tire inlating pumps, and more particularly to air pumps of the type adapted for readyl attachment to some means of support for holding the same firm during the manipulation thereof.

The object of my invention resides primai-ily in the provision of means in con- Y nection with a tire inflating pump for automobiles, whereby the pump may be clamped for its support to the running board of the automobile with a'minimum amount of effort and expenditure of time; further object resides in providing pumps of said type with means for clamping same to the running board by the single operation of a lever, whereby the same may be quickly attache-:l to or detached .from the ruiming board, and a material saving of time effected in said'operations as compared with screw operated means adapted for the same purpose. Another object resides in the` provision of a pump operati11g-leverand a clamping lever, and a removable handle adapted for operating either lever. A still further object is to provide the clamping means with an adjustable head, whereby, when once adjusted with relation to a particular running board in order to obtain the desired clamp` ing effect, no further adjustment will be required. y

TVith the `above and other objects in view, the invention in the preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which:

Figure 1 is a sine elevation of an air pump embodying the improvements.

Fig. 2 is a similar view seen from another direction, the running board of an automobile being shown in section.

Fig. 3 is a section of the clamping means taken on the line 3-3 of Fig. 2.

rlhe pump illustrated in the drawings is of a conventional type, and the particular type of pump employed is immaterial, in so far as the present invention is concerned. As shown, the pump comprises a cylinder 5,

Patented J111y` 20"`1920 Application fuea'nay 1o, 1919. serial N0.f29s,172. 7 Y f 'l a piston 6,v the piston rod 7 of wvhiclrisv pivotally connected with an operatingv lever 8, having a stub arm 9, adapted toflt the socketed endl() of a detachable, handle4 11. The arm 12 of the lever is formed with a cross-arm 13, the ends ofv which have pivotal `connection at 14 with the upper ends of swinging rods-15, the lower ends of which are pivotally supported 'at 16 upon the pump base 17, the functionof the parts-recited and the 'mode of operation of the pump being well'understood in the-art. j A j Preferably formed integral with the pump base -17 and depending from the marginal edge thereof, are spaced elongated bearing lugs 18, and a single upwardly ex-i tending bearing lug 19 Vin vertical alinement with a center line drawnbetween the lugs Y18. Pivoted between the lugs 18, as at` 2Q, is'Y an angle lever 21, one arm of whichlever extends beneath the pump base and carries a screw bolt 22 threaded therein. Adapted to rest upon said bolt 22,v` `is what f, may be termed'a bearing head 23, tapered` at its end 2st to fit betweenthe spaced lugs/18, and its opposite end provided with afined de-` pending pin 25 extending through an aperture in thelever, a coil spring 26 encircling board, may thus be both effectively e114,

gaged for clamping purposes, while at the same time the bearing head will be adapted for effectively engaging a ruiming board of uniform thickness.- Such adaptability is rendered possible because the bearing head is permitted to rock upon its supporting bolt 22, and by means of which bolt the bearing head may also be adjusted with relation to .Y

the lever which indirectly supports the same,

so that, within limits, the clamping means Y f i' may ie adjusted for leffectively engaging running boards of varying thicknessjand cross-sectional formation. i

The end of the lever 21, through which power is applied in the clamping operation, extends upwardly beside the pump cylinder lines,wlien the pivot connecting the toggle links slightly. over Center in the clamping: Y operation, the parts will .be effectively locked as shown, and has connection through a toggle, formed by the links 30 and link 3l, with the upper endofthe lug19, which interconnection of parts is effected through..

pivot members 32. The toggle link` 31 providedv with .an integrally formed stub handle portion 33, formed to fit the socketed end of the handle l1,v which latter thus serves for either operating the pump or the clamping means. As shown in Fig. 2 in full againstv self retraction'.

Vhile the foregoing is the preferred form of my invention, l' desire it to be understood Y that I do not limit myself to the precise upwardly with. respect thereto, a toggle op structurevshown and described, as it is obvivousthat the same may be variously modified without departing from the spirit of the invention. Y f y Vhat is claimed is l'. Arclamping means comprising a support, clamping means operative to and from the under side of the support including anangle lever, one arm of said lever extending beneath tlie support andthe other extending eratively connected Vwith the upper end of the lever, and means for operating the.

' y toggle.

y 2. A clamping means comprising a sup-v port,gclamping means operative to and frei-ii the under side of the support including an angle lever, one arm of said lever extending beneath the support, and the other extending upwardly with respect thereto, a toggle operatively connected with the upper end of the lever, and a handle carried by one of the toggle links Vfor operating the toggle.

3. A clamping means including a support, Y

an angle lever mounted thereon and in part extending beneatlitlie support, a screw bolt carried bythe lever, an elongated bearing Ahead adjustably vsupported for rocking movement by the bolt beneath said support,

and' means for preventingrelative lateral displacementbetween the bearing head and the lever.

' 4. A clamping means including asupport, a clamping lever mountedy on they support and in part extendingbeneaththe saine, an

elongated curved bearing head carried by Y the lever, and means for vertically adjusting the bearing headwith relation to the lever and to permit a tilting movement thereof.

5. A clamping means including a support, spaced bearing. lugs depending from the support, a clamping lever pivotally Asupported G. A clamping means includingasupport,

spaced .bearing lugs depending from` the support, a clamping lever pivotally supported between said lugs, a bearing -head having one end thereof freely extending between said lugs, and its opposite end carrying a depending pin freely passing tliroughan'aperture in said lever, means onthe lever yfor supporting the bearing' head in vertical and angular relation thereto, a toggle having connection` with the operative end of said lever, and ymeans for operating the toggle.V
